Generally, unless they ride in the car all the time, animals are not fond of being in the car. They think that they are going to the vet, perhaps?

Knowledgehound says "there are three primary reasons why your pet cries. One is that the car makes scarey noises and vibrates. Two is that pets often aren't able to see out of the window(s). And three is that most car rides end at the veterinarian's office."
